From a review of the first edition: "This book ] covers in depth a broad range of topics in the mathematical theory of phase transition in statistical mechanics. ] It is in fact one of the author's stated aims that this comprehensive monograph should serve both as an introductory text and as a reference for the expert." (F. Papangelou, Zentralblatt MATH)

The second edition has been extended by a new section on large deviations and some comments on the more recent developments in the area.

This monograph is an introduction to the theory of ordinary differential equations with jump conditions at discrete moments of time.

From the contents:

• Pulse differential equations and inclusions
• Linear systems with multivalued trajectories
• Method of averaging in systems with pulse action
• Averaging of differential inclusions
• Differential equations with discontinuous right-hand side

Graph models are extremely useful for almost all applications and applicators as they play an important role as structuring tools. They allow to model net structures - like roads, computers, telephones - instances of abstract data structures - like lists, stacks, trees - and functional or object oriented programming. In turn, graphs are models for mathematical objects, like categories and functors.

This highly self-contained book about algebraic graph theory is written with a view to keep the lively and unconventional atmosphere of a spoken text to communicate the enthusiasm the...
